To all whom it may concern:

Be itknown that 1, JOHN F. OHMER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Printing Devices for Ticket Printing, Issuing. and Auditing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same, reference eing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relatesto new and useful improvements in printing or impression devices having a special adaptation for machines for printing, issuing and auditing railway transportation tickets. The present improvements, so especially adapted, relate more specifically to the printing or impression roller or platen and the means for operating the same in a rotary and reciprocating manner, and to the inking devices, which apply ink to the type devices over which the roller platen passes in pressing the paper to take the print or impression, as will here-- inafter more fully appear from the description to follow. The present improvements are divided from my pending application for a patent on improvements in ticket printing, issuing and auditin machines, filed November 5, 1914, serial several, principally among which is to provide an improved form of roller platen mechanism for the type devices from which impressions or prints are taken, as well as to provide an improved form of inking appliance for inking the type devices, as Wlll more fully appear from a description of the same in connection with the accompanyin%draw1ngs.

eferrmg 1n general terms to the accompanying drawings, Figure 1 is a side elevation of an inking roller and platen or impression roller withthe operating mechanism therefor associated therewith; Fig. 2 is a similar elevation with the side plate and actuating mechanism removed; Fi 3 is a rear elevation with the type mem ers and supporting frame removed; Fig, 4 is a sectional elevation through the platen or im 0. 870,468., The objects of the said improvements are pression roller and the inking roller and partsassociated therewith in an elevated or printing position; and Fig. 5 is a detail perspective View of the ink fountain and the ink-applying roller.

In a detail description of the invention, similar reference characters indicate corresponding parts in the annexed drawings.

Referring more particularly to the drawings, 1 designates a shaft journaledin side frame plates 2 and 3. :The shaft 1 is operated from a crank 4 having a hand-grip 5 and has mounted thereon a gear 6 which is in mesh with a pinion 7 mounted on a studshaft 8 extending from the adjacent side plate 2. The crank 4 is also fixed to the said stud-shaft 8. Mounted on the ends of the shaft 1 and lying adjacent to the side frame plates 2 and 3 are two snail-cams 9 which are in positions to engage rollers 10 which are mounted on two angular levers 11 pivoted at 12 to the side plates 2 and 3. The ends of the levers 11 opposite the pivots 12 have connected to them side frames or plates 13, said frames or plates being pivoted to ends of said levers by pivots 14. Springs 16 exert a downward pull on said levers. Mounted in said side frames or plates 13, is a shaft 15 upon which the roller platen 16 is mounted. The ends of said platen are moved inwardly over the face of the printing devices, for example, the wheel 17 which contains type 18 and a stationary printing form 19. Such movement is given said roller platen 16 by the levers 11 through the cams 9. During the upward movement of the cams 9, during which the highest surfaces of said cams engage the rollers 10, the roller platen 16 is pressed against the printing devices by two levers 20 which are pivoted at 21 to the side plates 2 and 3. The pressure levers 20 are provided with flat faces 22 which engage the ends of the shaft 15 when the roller platen is in engagement with the type devices. The levers 20 are actuated to press the roller platen against the type devices 18 and 19 by springs 23 which are connected to pins 24 carried by the levers 20 and to tension levers 25 also pivoted at 21. The free ends of the levers 25 are adapted to engage cams 26 on the shaft 1. The positions of said cams 26 are such that when the roller platen 16 is moving upwardly. as in Fig. 4, the tension of the springs 23 will be exerted on the levers 20 thereby pressing the roller platen 16 against the printing devices. The object of providing a flexible connection between the v cams 26 and the levers 20 through the medium of the levers 25, is to compensate for any variable or unequal movement of the roller platen 16 when it is moving over the printing devices. The printing devices are inked previous to the-passage of the roller platen 16 thereover by a felt inking roller 27 which is mounted on levers 28 journaled on the shaft and controlled by springs 29 and given the necessary tension. When in a normal position, the inking roller 27 lies in contact with an ink-supply medium consisting of a trough 30 supported by cross member 31. The trough 30 is filled with a suitable absorbent material 32 which pro-. vides a reservoir for supplying the necessary ink to the inking roller. The roller platen 16 is rolled over the printing devices, for example, type 18 on wheel 17 and form 19, through the agency of gears 33 mounted on the ends of the roller platen. These gears 33 mesh with idlers 34 supported by brackets 35 extending from the side frames or plates 13. The idlers 34 are adapted to mesh with racks 36 carried on the upper parts of the levers 20 during the time the platen passes over the type devices it is revolved through the agency of the gears 33 and 34 and racks 36 thereby producing a print or impression after which the ink roller and roller platen are returned to their normal position, as in Fig. 2, through the continued operation of the crank 4. This operation of the crank 4 causes various other mechanisms, not herein illustrated or described, to be operated, as fully disclosed in my pending application herembefore referred to. The present invention relates to the roller platen and ink roller de vices and cooperating elements, therefore, the various other mechanisms, affected through the operation of the crank 4 have been 1 omitted.
